Stackdriver Debugger is a free, open-source way to debug your running
application without requiring a redeployment.
This library allows you to set breakpoints in your running application that
conditionally capture local variable state, stack traces, and more. This
library can work in conjunction with the PHP library google/cloud-debugger
(available via composer: https://packagist.org/packages/google/cloud-debugger)
in order to send collected data to a backend storage server.
Package built for PHP 7.1.
